Title: Tin oxide gas sensors
Inventor: MCGEEHIN PETER
IPC: G01N27/12
Filed: 1990-07-25
Abstract: A hydrogen and CO sensor of the kind comprising a pellet of fired, compressed SnO2 powder with a fine dispersion of platinum, has its porosity decreased by addition of a densifying additive before being compressed, so as to increase its selective sensitivity to hydrogen. The additive may be a firing flux which softens below or at the firing temperature such as felspar or bentonite or a temporary binder such as gum tragacanth. The resulting pellet preferably has a porosity substantially less than 50% and may be insensitive to CO. Sensors of different densities may be used in an assembly so that the amounts of CO and H2 present can be quantitatively evaluated individually.

Title: Image capture apparatus with increased dynamic range.
Inventor: VILIESID NICHOLAS ALFRED WILLI
IPC: H04N5/225
Filed: 1991-04-30
Abstract: An image capture apparatus (eg. a video camera) for producing video image signals includes an image sensor 33 for producing image signals having signal values representative of radiation intensity incident on respective positions of the sensor. The apparatus is able to identify an area of the sensor at which the incident intensity exceeds a predetermined intensity and to cause a stepped reduction in the image signal values corresponding to said area. The apparatus enables a range of intensity levels above a predetermined maximum to be translated or shifted 48 to within a range which can be accommodated, for example by a broadcast television system, in a manner equivalent to applying a negative pedestal to that range of intensity levels. Preferably, for detecting an area of the sensor at which the incident intensity exceeds a predetermined intensity, a sense array 44 additional to the image sensor is provided for producing sample signals representative of the radiation incident on the sensor at corresponding image positions. A programmable attenuator may be used to give the necessary signal range shift; alternatively a controllable optical filter (Figs 9, 13) may be used, or the integration time of the image sensor elements varied (figs 8 and 12). Instead of providing a separate sense array, signal amplitude may be determined from the image sensor output (figs 12, 13). <IMAGE>

An adhesive material of tin oxide, aluminium oxide, boron nitride, yttrium oxide, or Schott evaporation glass may be disposed between the substrate and the hard material. A light transmissive lubricous polymer, eg a silicone, polytetrafluorethylene or polyethlene, may be disposed over the lubricous coating material. The light transmissive hard material may be produced by a variety of processes, eg plasma sputtering, electron-beam evaporation, ion-plating or a reactive ion-beam sputtering technique. In any one of these processes the other layer may be made by the same technique.
